json.loads answers a bad value with "Expecting value: line 1 column 1 (char 0)",
which names neither the input at fault nor what it actually received. The
command has three string inputs; nothing in that message says which one broke,
so the operator is left guessing.
The mistake it hides is the obvious one. Documentation shows the input name and
the value together, so `terms_json: [{...}]` gets pasted whole into the value
field, and the parser then chokes on the field name it was handed. Echoing the
first 80 characters back makes that visible immediately.
Also carry a worked example in the manifest — the term that keeps only alerts
attached to an investigation, which is the filter this input mainly exists for —
and say explicitly to paste the array alone.
